What are the application scenarios of NB-IoT technical analysis and NB-IOT? I believe many inexperienced people are at a loss about this. Therefore, this paper summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

LPWAN,Low Power Wide Area Network, low power wide area network. The name has its two most important features: low power consumption and wide coverage. At present, the more mainstream are: NB-IoT, LoRa, Sigfox, eMTC. The full name of NB-IoT is Narrow Band IoT, or narrowband Internet of things (narrow bandwidth, slow speed).

NB-IoT performs well in all aspects except speed.

In terms of power consumption, NB-IoT sacrifices speed, but returns lower power consumption. The use of simplified protocol, more suitable design, greatly increased the standby time of the terminal, some NB terminals, the standby time claimed to be up to 10 years!

In terms of signal coverage, NB-IoT has better coverage (20dB gain), even if your water meter is buried under the manhole cover, it does not affect the signal transmission and receiving.

In terms of the number of connections, each community can support 50,000 terminals, which is quite tough. Even if there are 50, 000 pigs in this neighborhood, it is easy to monitor each one.

The most important thing is cost and price. No matter how awesome you are, if the cost is high, it will be in vain if the price is too high to afford. The cost of NB-IoT communication module is very low, and each module group is expected to be reduced to less than $5 or less, which is conducive to mass procurement and use.

Application of nb-iot

1. NB-IoT is applied to asset location and tracking system.

With the in-depth development of information and a variety of intelligent terminal equipment, the demand for personnel and asset positioning will continue to heat up. The application in the field of location service also shows the characteristics of fragmentation, such as the inventory of assets in the wisdom park, the tracking and disposal of medical waste, and the location of pets.

Nowadays, most of the trackers in the market are based on GSM in the wide area communication technology, and the power consumption is a big problem. Large chip area, high cost, relatively low coverage, etc., this technology happens to be contrary to the requirements of location trackers. However, the technology of GSM is quite backward, resulting in poor product experience of location trackers, while GSM in some countries has withdrawn or is facing withdrawal, resulting in a shortage of such products and technologies.

The birth of NB-IoT technology and its born low power consumption and deep coverage properties just make up for many shortcomings of traditional communication technology, which can produce connections for locating assets tracking objects in both indoor and outdoor areas. NB-IoT technology, which has the characteristics of low power consumption, wide coverage, low cost and small size, will become an indispensable way of communication in the field of asset tracking.

2. Application of NB-IoT in fire protection system (smoke sensor)

There are often fires in news reports, every fire is accompanied by the destruction of the family, and every scene is shocking. We should raise the awareness of fire fighting and make rational use of fire fighting equipment in order to minimize losses and injuries.

The smoke sensor is the sentinel of the fire control system, which can detect smoke in real time. If the smoke concentration exceeds the standard, the sensor will send information to the background server and start the alarm bell, broadcast horn and other related equipment. The server will automatically push the information to the relevant personnel and departments to achieve intelligent fire safety. In practical application, according to the requirements of fire protection, the installation of smoke sensor is dense, inconvenient to route and high cost.

The use of NB-IoT wireless smoke sensor can avoid the problem of difficult wiring and greatly save the installation cost; NB-IoT has a large number of connections, and the number of smoke sensors connected at the same time can reach more than 100, 000, which can satisfy the simultaneous access of a large number of smoke sensors; NB-IoT has ultra-low power consumption and can work in standby state for ten years, which greatly reduces the maintenance cost after installation. NB-IoT has super signal coverage, which can cover indoor and basement; NB-IoT is ultra-low cost, and the estimated price of the chip is as low as $1.

3. The application of NB-IoT in smart home (smart lock)

With the popularity of smart home industry in recent years, intelligent locks appear more and more frequently in daily life. At present, intelligent locks use non-mechanical keys as the technology for users to identify ID. The mainstream technologies are inductive card, fingerprint identification, password recognition, facial recognition and so on, which greatly improve the security of access control, but the premise of the above security is that under the condition of power on, if the intelligent lock is in a power-off state, the intelligent lock is nonexistent.

1. In order to improve security, you need

2. Intelligent lock has built-in battery

3. Collect all the basic data

4. Transfer data to the server

5. Alarm users automatically when abnormal data is collected.
